Nucleation is afirst-order transition involving a crossing in phase boundaries. Upon reachinga new equilibrium phase, thermodynamic stability develops. The phenomenon is universaloccurring in proteins, inorganic and organic processes. We will be focussing onatmospheric nucleation and its role in cloud condensation. Atmosphericnucleation is the irreversible aggregation of atomistic particles forming acluster/nucleus on attainment of a new phase.
The new phase concerns nanoscalechemistry with macroscopic results: growth. Governing the process is temperaturechanges, with pressure as a convex function to allow measurement of the GibbsFree Energy of the system. Although the study in this field stretches furtherthan half a century – the mechanism is still unfinished. It is as thoughresearching into this field provides a tiny piece of a puzzle of a board thatis continuously evolving.
Rendering that tiny piece either being partiallyapplicable or redundant to the board. Additionally, the nature of the researchinto this field is difficult. Researchers have found vibrational frequency ofatoms can act as interference clouding vision into the mechanism of nucleation.
This is due to atomic reactions sharing the same frequency as molecularvibrations. Hence, a comprehensive understanding of the mechanics of nucleationstill remains elusive. To current date, researchers cannot predict the exactmoment and location of nucleation.
